Systems and methods for visualizing navigation of a medical device with respect to a target using a live fluoroscopic view. The methods include displaying, in a screen, a three-dimensional (3D) view of a 3D model of a target from the perspective of a medical device tip. The methods also include displaying, in the screen, a live two-dimensional (2D) fluoroscopic view showing a medical device, and displaying a target mark, which corresponds to the 3D model of the target, overlaid on the live 2D fluoroscopic view. The methods may include determining whether the medical device tip is aligned with the target, displaying the target mark in a first color if the medical device tip is aligned with the target, and displaying the target mark in second color different from the first color if the medical device tip is not aligned with the target.

Examples of systems and methods described herein may utilize augmented reality devices and pointers in generating intra-operative plans and providing guidance for knee surgery. A pointer may indicate one or more anatomical points. An augmented reality device may detect positions of knee anatomical features based on a position of the pointer and positions of fiducials associated with a marker affixed to body part proximate to a knee, such as a femur or a tibia. The augmented reality device may generate a planned resection plane based on the positions of the knee anatomical features, and determine an actual resection plane based on a view of a resection guide having a marker inserted in the guide. The augmented reality device may provide guidance to position the guide to align the actual resection plane with the planned resection plane.

Some embodiments of the present disclosure provide a pneumothorax detection method performed by a computing device. The method may comprise obtaining predicted pneumothorax information, predicted tube information, and a predicted spinal baseline with respect to an input image from a trained pneumothorax prediction model; determining at least one pneumothorax representative position for the predicted pneumothorax information and at least one tube representative position for the predicted tube information, in a prediction image in which the predicted pneumothorax information and the predicted tube information are displayed; dividing the prediction image into a first region and a second region by the predicted spinal baseline; and determining a region in which the at least one pneumothorax representative position and the at least one tube representative position exist among the first region and the second region.

A robotic surgical system comprises a surgical tool, a manipulator configured to support the surgical tool, a force/torque sensor to measure forces and torques applied to the surgical tool, and a control system. The control system obtains a three-dimensional milling path for the surgical tool. The control system also receives one or more signals from the force/torque sensor in response to a user manually applying user forces and torques to the surgical tool. The control system determines a commanded pose to which to command the manipulator to advance the surgical tool along the milling path based on a tangential component of the user forces and torques, based on a virtual simulation using virtual constraints, and/or based on other suitable factors to promote guided, manual movement of the surgical tool along the milling path.

A surgical instrument having a first member being engageable with a fastener. A second member includes an expandable portion configured for capturing the fastener. A third member is engageable with the expandable portion to releasably capture the fastener. An actuator connected with the second member and the third member. The actuator includes a threaded inner surface and a threaded coupling member engageable with the threaded inner surface to facilitate axial translation of the second member relative to the third member. Systems, spinal constructs, implants and methods are disclosed.

An apparatus is provided that is visible by both a three dimensional (3D) scanner system of a medical navigation system and a camera of the medical navigation system. The apparatus involves a rigid member and a plurality of markers attached to the rigid member. Each of the plurality of markers includes a reflective surface portion visible by the camera and a distinct identifiable portion visible by the 3D scanner system. The apparatus further involves a connector mechanism to connect the apparatus to a reference location. The apparatus is in a field of view of the 3D scanner system and the camera within a timeframe of the 3D scan.

A spinal disorder diagnosis and treatment planning system is provided. The diagnosis and treatment planning system includes a mixed reality holographic display including at least one processor, at least one camera, at least one sensor, and being configured to acquire data points corresponding to a surface of a body adjacent to vertebral tissue. A computer database is configured to transmit imaging of the body including the vertebral tissue to the mixed reality holographic display. The mixed reality holographic display is configured to display a first holographic image of the vertebral tissue superimposed with a body image including the surface. Methods are also disclosed.

A surgical system includes an arm extending from the base and having a distal end configured to be coupled to a tool, a first marker coupled in fixed relation to the base, and a tracking system. The tracking system is configured to collect first data indicative of a position of the first marker and collect second data indicative of a position an anatomical feature of a patient. The surgical system also includes a processor configured to calculate a position of the tool relative to the anatomical feature based on the first data and the second data.

An example physical tracking tool includes a main body defining a channel configured to receive a tool, the channel having a longitudinal axis; and one or more physical tracking features attached to the main body, each physical tracking feature comprising a plurality of planar faces, each planar face of the plurality of planar faces including different a graphical pattern of a plurality of graphical patterns.

Disclosed are an ablation operation prompting method, an electronic device, and a computer-readable storage medium. The method includes: acquiring an image of an ablation site and displaying the image on a screen when an ablation task is triggered; acquiring position data of a currently-being-ablated target ablation point, marking the target ablation point in the image according to the position data; acquiring the elapsed ablation time and the temperature of the target ablation point in real time, and determining the ablation status of the target ablation point according to the elapsed ablation time and the temperature; and generating a schematic real-time dynamic change diagram of the target ablation point according to the ablation status, and displaying the schematic diagram on the screen, to indicate the real-time ablation status change of the target ablation point.
